ABSTRACT An apparatus for heating the operating cabin of a machine, uses as the heating medium, the oil in an internal- combustion engine, the said oil being raised to a high pressure by a hydraulic pump and being relieved-expanded in a throttle-element for heating, In order to accelerate the warming up of the internal-combustion engine, the flow of engine oil arriving from the hydraulic pump is fed to engine lubricating- or cooling-oil system in front of the bearing locations, In order to add to the supply of heat to some of the oil contained in the said engine, the hydraulic pumps draw in a partial flow of the engine lubricating and cooling oil, in short-circuit, after a lubricating-oil pump, Both of these measures facilitate the application of the apparatus to the lubricating oil system of internal-combustion engines.
